I have 2 of these heavy bi-pods, or should I say 2 halves. I bought 2 of these complete a couple of years ago, wrapped them up in old t-shirts, and after a 36hr. journey to get home, I realized I had lost or left the receiver locking pieces. And YES I do feel like a complete IDIOT!!!! I have searched everywhere for parts to no avail.. What to do with them now? I thought of have the parts made at my local machine shop, but without one for dimensions, where would you start?
